In this study, collagen peptides derived from yak bone (YCP) were prepared using an ultrasound-assisted immobilized enzyme hydrolysis system (US + IP-EH), and a comprehensive investigation was conducted into their structural characteristics, stability, and underlying antioxidant mechanisms. The results revealed optimal extraction conditions as follows: an ultrasonic power of 415 W, an enzymatic hydrolysis temperature of 49 °C, a hydrolysis duration of 8.4 h, an immobilized enzyme dosage of 3.6 %, and hydrolysis degree (DH) reaching 22.36 % in the validation experiment. Notably, the US + IP-EH approach significantly enhanced the yield, structural integrity, and antioxidant capacity of YCP, enabling them to retain robust antioxidant stability even under challenging conditions such as high temperatures, extreme pH (strong acids or alkalis), light exposure, and gastrointestinal digestion. Furthermore, ten novel antioxidant peptides were successfully identified, demonstrating non-allergenic and non-toxic properties. Among these, peptides P1, P4, and P10 exhibited favorable interactions with Keap1 by occupying its primary binding sites, thereby effectively disrupting the Keap1-Nrf2 complex structure.

This study investigates the efficacy of Cu/Ag/Zn trimetallic nanocomposites (TMNCs) as antimicrobial coatings for urinary catheters, synthesized via a green, ultrasonic–autoclave-assisted method. The nanocomposites were thoroughly characterized using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Fourier-transform infrared spectroscopy (FTIR), Raman spectroscopy, thermogravimetric analysis (TGA), Brunauer–Emmett–Teller (BET) surface area analysis, and field emission scanning electron microscopy (FESEM) to confirm their mesoporous, crystalline, uniformly distributed, and thermally stable nanoparticles. An optimized ultrasonic embedding technique was employed to uniformly coat TMNCs onto commercial urinary catheters, ensuring strong adhesion and consistent coverage. Antibacterial assays demonstrated concentration-dependent inhibition zones, reaching up to 21.5 mm for <em>Escherichia coli</em> and 24.0 mm for <em>Staphylococcus aureus</em>. Minimum inhibitory concentration (MIC) tests confirmed potent bactericidal activity, with MIC values of 32 µg/mL for <em>E. coli</em> and 64 µg/mL for <em>S. aureus</em>. Anti-biofilm assessments revealed that TMNCs matched or outperformed the efficacy of vancomycin, achieving up to 86.12 % inhibition for <em>S. aureus</em> and 73.59 % for <em>E. coli</em> at 2 × MIC. Cytotoxicity testing using U87 glioblastoma cells indicated good biocompatibility, with over 79 % cell viability at 0.1 mg/mL, followed by a dose-dependent decline at higher concentrations. Long-term stability studies conducted over 60 days under varied storage conditions confirmed the photothermal and colloidal stability of the TMNCs. In conclusion, Cu/Ag/Zn TMNC-coated urinary catheters demonstrated excellent antibacterial and anti-biofilm properties, biocompatibility, and long-term stability. These multi-functional coatings present a promising strategy for reducing CAUTI incidence and improving patient safety and clinical outcomes in urological applications.</div></div>","PeriodicalId":442,"journal":{"name":"Ultrasonics Sonochemistry","volume":"123 ","pages":"Article 107674"},"PeriodicalIF":9.7,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145499216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thermo-cylindrical type (55 °C) focused ultrasound was used for all experiments. Milk was subjected to focused ultrasound at 30 W and 100 W for 0, 10, 20, and 30 min to investigate the antimicrobial effects of this method. The total aerobic bacteria, coliforms, <em>Escherichia coli</em> O157:H7, and <em>Listeria monocytogenes</em> counts decreased (p < 0.05) with increasing focused-ultrasound power and treatment time. Thus, focused ultrasound treatments were applied at 30 W and 100 W for 30 min in subsequent milk quality evaluation and compared with LTLT-treated milk. The IgG retention value of milk treated with focused ultrasound at 30 W and 100 W was higher than that of LTLT-treated milk (p < 0.05). The alkaline phosphatase activity, pH, and whiteness index of milk treated with focused ultrasound at 100 W did not differ from LTLT-treated milk (p > 0.05). Moreover, milk treated with focused ultrasound at 100 W exhibited the smallest particle size and fat globules (p < 0.05). In conclusion, focused-ultrasound treatment at 55 °C and 100 W for 30 min improves milk microbial safety. Additionally, it preserves IgG activity and improves milk quality and stability by reducing fat globule size.

However, its practical applications are severely limited due to extremely poor aqueous solubility, which directly leads to low bioavailability. While polysaccharides like <em>Lycium barbarum</em> polysaccharide (LBP) can partially improve curcumin solubility, their solubilization efficiency remains limited. To overcome this challenge, we implemented ultrasonication as an effective processing strategy to enhance LBP’s capacity to promote curcumin dissolution. Our findings show that ultrasound-induced cavitation and related physico-chemical effects markedly improve LBP’s solubilization performance. The ultrasonically-assisted curcumin-LBP complex (CL-U) was systematically optimized through response surface methodology (RSM), identifying ultrasonic power, duration, and temperature as critical parameters. Extensive characterization verified that ultrasonication is essential for producing spherical core–shell nanoparticles, achieving a 2.23-fold enhancement in drug loading efficiency along with superior colloidal stability. Additional evidence from FTIR spectroscopy and acid hydrolysis experiments confirmed that ultrasonication reinforces hydrogen bonding as the principal intermolecular interaction stabilizing the complex. Biologically, CL-U demonstrated rapid cellular uptake in 4T1 cells within one hour and showed substantially improved antioxidant performance in both DPPH and ABTS assays. These functional gains are directly linked to the ultrasound-mediated improvements in solubility, stability, and bioavailability.
